Patent DE-3008169-A1 (DE)
Title: Elastomer conveyor belt - with force absorbing core separated by antistick agent from replaceable cover layers
Inventor: BRAEUTIGAM JUERGEN ING GRAD
IPC: B65G15/34
Filed: 1980-03-04
Abstract: A rubber or elastomer conveyor belt consists of a core which absorbs all tensile stresses and consists either of parallel steel ropes, embedded in rubber, or of two woven textile webs, impregnated with rubber. The core is prepared separately and is made endless by conventional techniques. The top and bottom covering layers are wound in the longitudinal direction around the core. They consist of woven textile lengths or of thermoplastic foils, separated from the core by a layer of a non-stick agent. This ensures that a conveyor belt can be repaired in a short time by replacement of a worn top cover.

Title: Seal for flap on tipper lorry - has elastic gasket in stepped seal space
Inventor: FINSTERBUSCH PETER
IPC: B62D33/033
Filed: 1980-03-05
Abstract: The rear flap for a tipper lorry with a seal to prevent loss of small granular load such as cereal has the flap pivoted about its upper edge and with the bottom edge closing against a step (32) at the rear of the load surface. The step has a flexible seal (11) while the locking catch (4) is protected by a sill (9) formed from one edge of the chassis frame. The sill has a turned over edge (10) to protect the catch from damage by loading equipment and has cut-out slots to take the locking tags (28) at the bottom of the flap. The flap is securely sealed to protect fine granular loads without danger of straining the flap and causing leaks.
Patent DE-3009882-A1 (DE)
Title: Laminated tubes made by powder metallurgy and hot extrusion - where intermediate metal sheath prevents diffusion between two layers of different powders
Inventor: AASLUND CHRISTER
IPC: B22F3/20
Filed: 1980-03-14
Abstract: This is an addn. to 2846660, which described a tube blank made of at least two layers of different materials, e.g. carbon and stainless steel powders made by shotting and consisting of spheroids. The layers are compacted in a capsule, and cold isostatically pressed to min. 80% of the theoretical density to make a tube blank, which is then hot extruded. In this addn. the presence of transition zones between the two layers, caused by diffusion, is prevented by using a sheath, pref. made of Ni or similar material, between the two powder layers in the capsule. The Ni or similar sheath prevents the diffusion of alloying elements, esp. carbon, between the powder layers; such diffusion can seriously impair the quality of the composite laminate.

Title: Automatic control for fill-in flash - has separate detector for available light and circuit to determine relative intensities of flash to natural light
IPC: G03B15/05
Filed: 1980-04-09
Abstract: The fill-in flash control has separate photocells to monitor the reflected flash as well as to provide a signal level for the background illumination. The correct exposure is determined taking film speed into account as well as the relative short time the electronic flash operates w.r.t. the steady background illumination.

Title: Method and apparatus for sinking directional boreholes
Inventor: STEUFMEHL WILLI
IPC: E21B4/18
Filed: 1981-01-31
Abstract: When drilling by means of a drilling tool which can be rotated via a string of drill pipes, the requirements for the desired verticality or rectilinearity are to be fulfilled in a favourable manner. To this end, the drilling tool in the stationary state is put into a suspended position at the string of drill pipes. After this a guide direction is first of all set for the drilling operation in accordance with a measured value and then operational fixing of the guide direction is carried out while maintaining this setting. An apparatus for carrying out this method has a bracing device in an area adjoining the drilling tool and, separate from the bracing device, a setting device with supporting members which can be displaced inwards and outwards (Fig. 1). The invention is especially suitable for the sinking of relatively large boreholes, for instance large-diameter holes, shafts or the like. <IMAGE>

Patent DE-3108507-A1 (DE)
Title: Turbine which can be driven by a fluid
Inventor: STRAUSAK BENEDIKT
IPC: F03C2/30
Filed: 1981-03-06
Abstract: A rotor (5) is eccentrically and pivotably mounted inside a housing (1) with a cylindrical inner surface (2). Carrier plates (8) extending radially outwards are rigidly fixed to the rotor. Between each carrier plate and a support plate (10) assigned to each carrier plate an elastic turbine blade (9) is clamped. The blade is deflected to a greater or lesser degree depending on the position of the turbine blade inside the housing. From a certain deflection upwards the turbine blade bears on the outer bent off edge of the support plate. Since with further deflection of the turbine blade only a short section of the blade is crucial to its springing after coming to bear on the support plate, the effective spring constant is rapidly increased so that the force with which the edge area of the blade is pressed on to the said inner surface is great. The result of this is that the contact pressure is small for a slight deflection of the turbine blade, resulting overall in lower losses due to friction.   <IMAGE>

Title: Apparatus for agitating and ventilating liquid manure
Inventor: SEIBOLD ERNST
IPC: B01F7/00
Filed: 1981-06-11
Abstract: Agitating and ventilating appliance for processing liquid cattle, hen and pig manure, having one or more airpipe assemblies which rotate about the trench axis via a gear and which feed fine-bubble air to the liquid manure from below, for example via a rotary compressor connected fixedly in terms of rotation to the gear. By means of the galvanised airpipe bundle sweeping slowly over the trench bottom at a short distance and having stepped air outlet pipes, a uniform intensive homogenisation of the liquid manure is achieved via the oxygen-rich air introduced, without the need for the customary additional agitator devices. Via a control system with automatic adjustable switching means, only short ventilation times of up to 5 minutes maximum are needed three times a day for liquid cattle manure, whilst only a maximum of up to 3 minutes 6 to 8 times a day are needed for processing liquid pig manure. Accordingly, in the novel appliance for agitating and ventilating liquid manure, an energy-saving drive motor of approximately 1.88 kW/2.5 hp is sufficient for a cylindrical liquid-manure container of a diameter of up to 18 m.

Title: Slide ring packing
Inventor: BERGLOEFF DAG DIPL ING
IPC: F16J15/34
Filed: 1981-07-29
Abstract: The invention relates to a slide ring packing for a high-pressure shaft seal on boiler feed pumps, main refrigerant pumps or the like, having two base rings of which the one corotates with the pump shaft and the other is fastened in the pump casing in an axially displaceable manner and can be moved up to the rotating part. For the purpose of forming the sealing surface, additional sliding rings are provided which bear on the base rings. An object of the invention is to achieve equalisation of the different inverting moments and axial forces which have an adverse effect in conventional designs, and to do so using ceramic solid plates which ensure long useful lives. To this end, according to the invention, the base rings (5, 12) are provided, on the side of the sliding rings (18, 19) bearing thereon, with annular equalisation ducts (21, 22), which alternately communicate, via holes (20, 23), with the high-pressure section (25) and the low-pressure section (24) of the pump. <IMAGE>
